An analytical drilling force model and GPU-accelerated haptics-based simulation framework of the pilot drilling...

Area of Science:

• Biomedical Engineering
• Dental Surgery Simulation

Background:

• Micro-implant placement is a common dental procedure.
• Training for this procedure requires tactile feedback to avoid complications like tooth root damage.

Purpose of the Study:

• To develop a haptics-based simulation framework for micro-implant pilot drilling.
• To train orthodontists using tactile sensation for safer and more effective surgery.

Main Methods:

• A voxel-based approach modeled inhomogeneous oral tissues.
• A preprocessing pipeline refined patient-specific data for an accurate oral model.
• An analytical drilling force model provided physically based haptic feedback.
• Graphics Processing Units (GPUs) were utilized for real-time performance optimization.

Main Results:

• A prototype system demonstrated effective rendering of drilling forces across tissue layers.
• The simulation framework reduced cycle time for the procedure.
• Visual display quality was enhanced within the simulation.

Conclusions:

• The haptics-based simulation framework is effective for training micro-implant surgery.
• The system enhances tactile learning and reduces the risk of damaging tooth roots.
• The use of GPUs significantly improved the real-time responsiveness of the simulation.
